He's just a bodybuilder who cuts through the crap and tells you in basic terms how to achieve your goals. For instance, if your goal is to get six pack abs, you might assume (as I did) that doing a sit load of shit-ups is the answer. Not everyone can afford a personal trainer.
He built a library of videos demonstrating how to safely perform exercises and lifts, always emphazising good form and nutrition, never judgemental, always understanding that there's gonna be someone out there who can't even bench the bar, and figuring out advice for beginners.
TBH, he did say that he's probably done everything he could do for beginners, but it's still a shitty thing to do. Plus the fact that his forum was probably the only place where you wouldn't be scorned (too much) for asking newby questions, and wasn't full of a$$holes bragposting about their gainz.
